The Design of Data Acquisition and Processing System Based on

LabVIEW

Abstract:As a kind of virtual instrument based on graphical programming the new

concept of instruments, run at the computer as a medium, save a large amount of display, control hardware, more and more shows its unique advantages. Data acquisition and processing system based on LabVIEW, and the overall adopted loop structure and order structure, in the form of the combination of the dynamic analog signal acquisition and real-time display, and the simulation of the data collection and alarm function, and the ability to store data, for a variety of Settings, display effect is good, the reality of the data acquisition and processing system has a great reference.
